DESCRIPTION
The DG2037/2038/2039 are dual single-pole/single-throw
monolithic CMOS analog switch designed for high
performance switching of analog signals. Combining low
power, fast switching, low on-resistance (r_DS(on):
3.0 W @ 2.7 V) and small physical size, the
DG2037/2038/2039 are ideal for portable and battery powered
applications requiring high performance and efficient use of
board space.
The DG2037/2038/2039 are built on Vishay Siliconix’s new
high density low voltage process. An epitaxial layer prevents
latchup.
Each switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
